No, you're on mastodon.social. Your address is:

@ RevNancyFitz @ mastodon.social

(but without the spaces)

You can see your address on your profile page and your posts just below your name in slightly darker letters.

Mstdn.social is a different server altogether owned by someone else (Yes, I know... they probably should have chosen a less confusing name! 😁 ).
